I would seriously consider the fuel you will be running as well. Perhaps Roelof will add some input but I would take a guess and recommend you run a lower oil content and run it rich to aid with cooling. If you run a high oil content and rich you will very likely damage your bearings quickly trying to compress a wet oily mix. Perhaps even 16% nitro too...

With your wheels spinning in rally and not much ventilation she will get hot.

Also the tuning will make all the difference, perhaps running a richer bottom end and run a smaller venturi to restrict the amount of air at lower rpms, which all then has to beg to question, why run a hi-performance Hi-RPM On Road engine?

I'd still go with a NovaRossi, the metalurgy, build and quality will give you reliability, it will be a better and longer lasting investment, providing the application of the engine is setup to the conditions you want to run in.


These are just considerations I would have, dont take any of it as gospel. I'd want more experienced engine ppl to give you the heads up than me.
